To. all whom t may concern:

j Be it known thatwe', GEORGE A. K EEsE, y Franciscoy county of San Mateo, State ofCalifornia, and lROBERT A'. ssEN, ofthe city andJ county of San Francisco, State of California, citizens of the United States, have invented new and useful Improvements in Curb-Plates, of

which the following is a specilication..

This invention relates to a curb bar or armor platefor concrete structures, such as One of the objects of the present invention simple, substantial cheaply with means formed integral therewith for concrete structure ,n it protects, in 'such a manner that it formsQ an integral part therewith when` the concrete sets.

Another object of the invention is to so plateI that it may be built in' construct the orf'placedv-in position within the form before theconcrete is poured, and further'- more, to bend or shape the plate and'key members to prevent formation of air pockets Further objects will hereinafter appear. he invention consists of the parts and the construction and combination of parts, as v hert-ainafter 4more fully described and claimed, havingreference to the accompanywhich; f

Fig. 4 is avlew similar to Fig. 3 showing the is bent, as at 2 to' form acurved face which partly covers the outside cornerof the-curb, indicated at B. This plate may-be made in lengths, suchl as maybe required and may be formedA by rollersor like machinery, not here shown'. g p

n members 3 lhave been provided. These are formed by cutting or slotting the face or side of the plate, as indicated at 4 and the metal thus cut is preferably bent in to assume an angle with relation to the face of the plate, as is indicated in Fig. 3, or the tangs or key members 3 may be bent on angles to the .face of the plate, so that they will assume positions opposite to each other, as indicated at 5, in Fig. 4.

For 4the purpose of further insuring a perfect lock between the concrete and th plate, a hook-like 4bend 6 may be formed onvtheinner end of each' tang or key 3. A curb armor' or plate constructedv as here shown may be built or set in a woodenform before` theL concrete is poured 'and the shape -of it'is such that no formed into which the concrete will not pockets or spaces are readily flow. The curve 2 on the upper ledge of the barris furthermore such that no air can possibly pocket under same.`v A
